Gmake did not cure this failure:

It is possible that an older version of gmake was used, so I am going to try a
new build where I explicitly name the gmake by its complete pathname.
Makefile contains the lines to create six symlinks. Could there be a timing
problem? These old Macs have a file system that "supports" a minimal time
difference between time stamps that is *two* seconds…
